If you dont understand means, just consider am selecting a date. Then i have get start date and end date of a week

Well, it seems the first step is to get the day of the week for the date you're interested in. The Calendar class can do that - look at the get method and the DAY_OF_WEEK constant in the Javadocs.

Once you've got that, you can roll the date forward/back the right number of days. The Calendar.add method will do that for you.
